In the 2015 Citadel founder Ken Griffin divorce case, ex-wife Anne Dias listed about $1 million in monthly child-related expenses in court filings
According to reports by several U.S. media outlets in 2015, including CNBC, ABC News and the Chicago Tribune, during the divorce proceedings in Cook County, Illinois, between Citadel founder Ken Griffin, whose wealth was then estimated at about $5 billion, and his ex-wife Anne Dias, financial disclosure documents filed by Anne Dias showed that she claimed maintaining the lifestyle of their three young children, then about 2, 4 and 7 years old, required about $1 million in monthly expenses.
Monthly items listed in the court documents included about $300,000 in private jet expenses, about $160,000 in vacation lodging, about $60,000 in office and professional personnel expenses, as well as about $6,800 in groceries and about $2,000 in stationery. Griffin’s side argued in court filings that part of these expenses belonged to the ex-wife’s personal lifestyle rather than being purely necessary for the children, and that he had paid for “nearly all child-related expenses.” Anne Dias’s side said that the figures reflected the lifestyle the children enjoyed during the marriage and sought to overturn the prenuptial agreement, under which she could receive about 1% of her husband’s assets, then estimated at about $50 million.
The divorce case was settled in 2015, and the prenuptial agreement was upheld in key respects; the specific child support and property terms were not fully disclosed.

This case took place under Illinois law, where the principle that children are entitled to maintain the lifestyle they had during the marriage makes the calculation of “standard” expenses in high-net-worth divorces extremely broad. The figures listed by Anne Dias came mainly from financial disclosures on her side, while Griffin’s side explicitly challenged some of them as luxury items not strictly necessary for the children and said he had already covered the children’s expenses. The media-reported “$1 million monthly bill” is a public presentation of the litigation positions of both sides, not the child support amount ultimately ordered by the court.
The case was settled in 2015, and the core terms of the prenuptial agreement were upheld, showing that courts still value the enforceability of agreements in high-net-worth cases. Griffin’s net worth at the time was far below its later peak, and the figures reflect claims made at a particular stage of the litigation rather than a long-term actual payment standard. In cases like this, it is common for both sides to disclose and rebut expense allocations through court filings, and settlement terms are often confidential.
ABAB News · Law of cognition
Expense claims in court filings do not equal amounts actually ordered or paid.
In high-net-worth divorces, the principle of maintaining the lifestyle during the marriage makes child-related expense calculations highly subjective and should be reviewed in light of both sides’ claims and the final settlement.
